std::chrono::year::operator+,std::chrono::year::operator- \- std::chrono::year::operator+,std::chrono::year::operator-

.SH Synopsis
   constexpr std::chrono::year operator+() noexcept; \fB(1)\fP \fI(since C++20)\fP
   constexpr std::chrono::year operator-() noexcept; \fB(2)\fP \fI(since C++20)\fP

   Applies the unary operators to the year value.

   1) Returns a copy of *this.
   2) Returns a year whose year value is the negation of that of *this.

.SH Return value

   1) *this
   2) std::chrono::year(-int(*this))

.SH Example


// Run this code

 #include <chrono>
 #include <iostream>

 int main()
 {
     constexpr std::chrono::year y{2020};
     constexpr auto ny = -y;
     std::cout << "The year " << (int)y << " negated is " << (int)ny << '\\n';
 }

.SH Output:

 The year 2020 negated is -2020
